So I work in a library.
So sometimes I pick up books.
Here are two of those. On the same topic, i.e. the propensity of people to believe in fake stuff.
Here they are:
Quantum Leaps in the Wrong Direction : Where Real Science Ends...and Pseudoscience Begins
Frauds, Myths, and Mysteries: Science and Pseudoscience in Archaeology
It seems that the major difference between science and pseudosciences is where you begin. If you begin with an hypothesis and then explain away evidence that shows your hypothesis to be full of hocus-pocus, it's not science. If other people can't duplicate your results, it's not science. If your hypothesis can't be falsified, it's not science.
I recommend these books for anyone wanting to indulge in a bit of light reading on the subject of The Silly Stuff People Believe and Why They Believe it.
